They can also be executed alone or in combination. It is then executed together with some methods in other related technologies; the embodiments of the present disclosure do not limit this.

In order to facilitate understanding of any embodiment of the present disclosure, first, the application scenario of frequency band search is described.

In one scenario embodiment, the terminal is a dual-SIM terminal, including Card 1 and Card 2. When the terminal moves to an area without an independent networking network SA, the network will be dropped during the switch to LTE.

In one embodiment, card 1 supports SA and card 2 is registered on LTE. The terminal moves from an area that supports SA to an area that does not have SA signal coverage. During the movement, the network will trigger LTE measurement and control.

In one embodiment, before the end of the terminal LTE measurement and control, the network will deliver the NR5G RRC OTA Packet--DL_DCCH/RRC Release message. This message can instruct the terminal to blindly redirect information to other SA frequency points.

In one embodiment, if a suitable cell cannot be found on the SA frequency point, the terminal will trigger a full-band search of NR. Here, the SA full-band search depends on the searched frequency band and the LTE paging cycle of card 2;

In one embodiment, when the searched frequency band remains unchanged, it depends on the LTE paging cycle of card 2, because when the paging opportunity of card 2 comes, card 1 will tune away and cannot perform the tune-out time. Band search operation.

As shown in Figure 1, this embodiment provides a method for network switching. The method is executed by a terminal equipped with dual cards. The method includes:

Step 11. In response to determining that the terminal has moved out of the signal coverage area of the first network registered by the first user identification module and the first user identification module triggers a full-band cell search for the second network, according to the signal coverage area of the first network registered with the second network Frequency points: determine the target frequency band supported in the area where the terminal is located from the frequency bands supported by the first user identification module;

Step 12. Search the cells of the second network based on the target frequency band to obtain the target cell;

Step 13: Switch the first user identification module to camp in the target cell.

Here, the terminal may be, but is not limited to, a computer, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device and/or a medical device, etc.

In one embodiment, the terminal is a mobile terminal, and the mobile terminal may be a multi-SIM terminal. A multi-card terminal is a terminal containing a multi-user identification module. The multi-card terminal may be: a terminal including at least two user identification modules, for example, a dual-card terminal or a three-card terminal. The behavior mode of the multi-user identification module terminal can be dual card dual standby single pass, dual card dual standby dual pass, three card triple standby, etc. The subscriber identification module may be a Subscriber Identification Module (SIM, Subscriber Identification Module) card that exists in a separate form or an integrated Subscriber Identification Module (e-SIM, embedded Subscriber Identification Module) that exists in an integrated form inside the terminal. It should be noted that card 1 and card 2 in this disclosure may be the user identification module.

In one embodiment, the dual-SIM terminal includes a first user identification module and a second user identification module. It may be that the first user identification module registers in the first network (for example, SA network) and establishes a network connection with the first network; the second user identification module registers in the second network (for example, SA network) , LTE network) to register and establish a network connection with the second network. In response to determining that the terminal moves out of the signal coverage area of the first network registered by the first user identification module and the first user identification module triggers a full-frequency cell search for the second network, according to the registered frequency point of the second network, Determine the target frequency band supported in the area where the terminal is located from the frequency bands supported by the first user module; search for the cells of the second network based on the target frequency band to obtain the target cell; identify the first user The module switches to camp on the target cell. Here, it should be noted that before executing this embodiment, the terminal will detect whether the terminal is a multi-SIM terminal, and the steps in this embodiment will be executed only when the terminal is a multi-SIM terminal.

In one embodiment, the terminal determines whether the terminal moves out of the signal coverage area of the first network registered by the first user identification module based on the received signal strength of the first network.

In one embodiment, the terminal receives indication information sent by the second network, where the indication information indicates frequency information of the second network for blind redirection by the terminal. The first user identification module searches for a cell of the second network on the frequency indicated by the frequency information of the second network. In one embodiment, if a cell is searched, the first user identification module is switched to camp on the searched cell. If no cell is found, the first user identification module triggers a full-frequency cell search operation for the second network to search for a suitable cell on the full frequency band.

In one embodiment, the full frequency band may include multiple frequency bands, and each frequency band will have a corresponding frequency point. The terminal may perform a frequency band search on the frequency band corresponding to the frequency point. In one embodiment, the terminal will detect the number of frequency bands included in the full frequency band.

Determine the target frequency band supported in the area where the terminal is located in the full frequency band, and search the cells of the second network based on the target frequency band to obtain the target cell; switch the first user identification module to reside on the target community. For example, according to the SA historical registration record, it can be determined that the frequency bands including N1, N3, N5, and N8 are supported in the area where the terminal is located, and the network side does not support the frequency bands N3, N5, and N8, then it can be performed only on N1. Cell search, in this way, can shorten the time of searching for a cell.

In one embodiment, the quantity threshold may be determined according to a delay requirement parameter of the handover network. Exemplarily, in response to the delay requirement parameter of the switching network being greater than the delay threshold, it is determined that the quantity threshold is greater than a predetermined value; or in response to the delay requirement parameter of the switching network being less than the delay threshold, it is determined that the quantity threshold is less than the predetermined value value. In this way, the quantity threshold can be adapted to the delay requirement parameters of the handover network.

In one embodiment, before searching for cells of the second network based on the target frequency band, the paging cycles of neighboring cells of the cell to which the second user identification module is connected are detected. When it is determined that the difference between the paging cycle of the neighboring cell and the paging cycle of the cell connected to the second user identification module is greater than the difference threshold, the second user identification module may switch to communicate with the neighboring cell. area to establish a connection. Here, the difference threshold may be determined according to the delay requirement parameter of the handover network. Exemplarily, in response to the delay requirement parameter of the switching network being less than a parameter threshold, it is determined that the difference threshold is greater than a predetermined value; or in response to the delay requirement parameter of the switching network being greater than the parameter threshold, it is determined that the difference The value threshold is less than the predetermined value.

In one embodiment, before searching for cells of the second network based on the target frequency band, the signal strength and paging cycle of neighboring cells of the cell connected to the second user identification module are detected. When it is determined that the difference between the paging cycle of the neighboring cell and the paging cycle of the cell connected to the second user identification module is greater than the difference threshold and the signal strength is greater than the strength threshold, the second user identification module may Switch to establish a connection with the neighbor cell. Here, the intensity threshold may be determined according to a communication quality parameter. Exemplarily, in response to the communication quality parameter being greater than the parameter threshold, it is determined that the intensity threshold is greater than a predetermined value; or in response to the communication quality parameter being less than the parameter threshold, it is determined that the intensity threshold is less than the predetermined value.

In an embodiment of the present disclosure, in response to determining that the terminal moves out of the signal coverage area of the first network registered by the first user identification module and the first user identification module triggers a full-band cell search for the second network, according to the registered For the frequency point of the second network, determine the target frequency band supported in the area from the frequency band supported by the first card; search for the cells of the second network based on the target frequency band to obtain the target cell; convert the third A user identification module is switched to camp on the target cell. Here, since the terminal searches for the cell of the second network based on the target frequency band, and the target frequency band is a frequency band supported in the area where the terminal is located determined from the frequency bands supported by the first user identification module, correspondingly Compared with the method of searching the cells of the second network in the whole frequency band, the frequency bands that need to be searched are reduced, which can reduce the time of frequency band search and quickly switch to the target cell to ensure the reliability of wireless communication and bring benefits to users.

Target frequency bands supported by the region.

In one embodiment, the full frequency band may include multiple frequency bands, and each frequency band will have a corresponding frequency point. The terminal may perform a frequency band search on the frequency band corresponding to the frequency point. Here, when the number of frequency bands is greater than a predetermined value, the time for cell search in the full frequency band will be greater than the time threshold.

In one embodiment, after the full-band cell search is triggered, the terminal detects the number of frequency bands included in the full-band. For example, when the number of frequency bands included in the full frequency band is greater than the quantity threshold, the target frequency band supported in the area where the terminal is located will be determined from the full frequency band based on the historical registration records of the SA frequency points of the second network that were previously registered. , and search the cells of the second network based on the target frequency band to obtain the target cell; switch the first user identification module to reside in the target cell. When the number of frequency bands included in the full frequency band is less than the frequency band threshold, a cell search can be performed based on the full frequency band to obtain a target cell; and the first user identification module is switched to reside in the target cell.

It should be noted that the number of target frequency bands is smaller than the number of frequency bands included in the full frequency band. In this way, the number of frequency bands that need to be searched is reduced, and the probability of frequency band search can be shortened. And because the target frequency band is determined based on the historical registration record of the SA frequency point of the second network that was previously registered, the probability of successful cell search will increase.

In one embodiment, the quantity threshold may be determined according to a delay requirement parameter of the handover network. Exemplarily, in response to the delay requirement parameter of the switching network being greater than the delay threshold, it is determined that the quantity threshold is greater than a predetermined value; or in response to the delay requirement parameter of the switching network being less than the delay threshold, it is determined that the quantity threshold is less than the predetermined value value. In this way, the quantity threshold can be adapted to the delay requirement parameters of the handover network.
